Вычислите, представь обыкновенную дробь в виде десятичнойпомогите срочнооо!!!!

• 2(3/10) + (1.5-0.7) =

1. 2(3/10) = 23/10 = 2.3
2. 2.3 + (1.5-0.7) =
3. 1.5 - 0.7 = 0.8
4. 2.3 + 0.8 = 3.1

• 6(3/4) - (2.35+0.23) =

1. 6(3/4) = 27/4 = 6.75
2. 6.75 - (2.35+0.23) =
3. 2.35 + 0.23 = 2.58
4. 2.35 + 2.58 = 4.17

• 3(2/5) - (0.9+0.45) =

1. 3(2/5) = 17/5 = 3.4
2. 3.4 - (0.9+0.45) =
3. 0.9 + 0.45 = 1.35
4. 3.4 - 1.35 = 2.05

• (12.4-9.35) + 2(12/25) =

1. 2(12/25) = 62/25 = 2.48
2. (12.4-9.35) + 2.48 =
3. 12.4 - 9.35 = 3.05
4. 3.05 + 2.48 = 5.53

• (27.61-8.11) + 4(1/20) =

1. 19.5 + 4.05 = 23.55

• (6.35-2.05) + 9/10 =

1. 4.3 + 0.9 = 5.2
